In the mid 80s, I had (and still have) a Sperry PC, an 8088 IBM PC clone with a crazy "hi resolution" graphics adapter that was two full length cards with a bridging cable and more memory than the motherboard. Doing all my programming in assembly language at the time, and not having the money for an 8087 math coprocessor, I bought the Mark Williams Let's C compiler to have a floating point library to draw Mandelbrot sets. I quickly decided it was a shame to let a perfectly good compiler go to waste and learned C. Most 640x400 images were taking 25-32 hours to produce, depending on where they were. I started writing a fixed-point library, and then found Fractint and just wrote a graphics driver for the Sperry adapter. The same images generated in only 8 minutes. Tell that to the kids today, and they won't believe you.
